HAND BRAKE SYSTEM

HAND BRAKE SYSTEM

In vehicle there are two brakes  paddle brake and hand brake.

Hand brake also named as parking brakes or emergency brakes. 

mostly this brake is applied for rear wheel by the mechanism of  steel wire or pressure system.

Use of hand brake

Its is used as a parking brake to stop the car at one position the rear wheel gets lock even you give gas to your vehicle it will not move until or unless hand brakes are damage.

It prevents to flow back or reverse in direction.

Never apply hand brakes when you are in speed or else with no time vehicle will start rolling over.

WHEEL HUB GONE BAD

WHEEL HUB GONE BAD

This round circular thing is present with alloy rims and wheel basically its a support to Tyre and alloy rim is attached to it with mean of 4-6 nut bolts.

Wheel hub have bearings with in it and which rotates with Axial.

What if wheel hub goes damage? Is it possible?

YES, every wheel hub have bearings in it with coverage of maximum miles of 40-50 thousand that is an average. The bearing damage its life is over.

What possibly can happen if Wheel hub goes bad?

If wheel hub goes bad their might be a chance of wheel to get broken which is serious and suppose that all happens when you are in high speed your car can turn over. 

WHAT are the symptoms of damage wheel hub?

1. vibration in wheel.
2. while applying brakes vehicles gets out of balance.
3. wheels are not balanced.

How can we observe the bad sound of wheel hub?

Drive slowly on a smooth road and closely observe the sound coming you will recognize the sound easily. 

TOP 3 ISSUE IN STARTING ENGINE

TOP 3 ISSUE IN STARTING  CAR ENGINE

Troubleshoot Car Engine

There may be many problems but TOP 3 problems are basic and one should find-out first where the problem lie? 

Here are the three reasons

Mechanical problem

Electrical problem

Fuel problem

Mechanical problem

Main-factor in troubleshoot engine in mechanical work is your engine parts are not working properly and there like TIME BELT, TIME BEARING , GAS KIT, PISTON, etc one should identify first that which part is defected and what is the function of that part? only then one can fix it.

Electric problem

The main issue which mostly occurs is electrical issue. This issue is common but mostly people get temporary solution main-factors includes BATTERY LINKED ISSUE, WIRING ISSUE, STARTING ISSUE, OLD REMOTE, etc you need to check it every month or periodically by an authentic expert to have safe and trouble free ride.

Fuel problem

IF you have empty tank that will be money issue not car but if your fuel pump is not working the engine will not start and if the car  do not pass the current to fuel pump then again you will have trouble. Check the current with fuse current.

Sensors

What is the function of Engine Sensors and what are they?

A modern car’s Engine Management System consists of different vary of electronic and electrical parts. It contains engine sensors, relays, and actuators that job along. they supply the car’s Engine management Unit with important knowledge parameters essential to manipulate numerous engine functions effectively. typically speaking, Engine sensors are the Electro-mechanical devices that monitor numerous engine parameters. Associate engine uses different kinds of sensors. They are Thermo-couples, Resistance Temperature Detectors (RTDs), and Hall result sensors.

 Types of Engine Sensors:

A thermometer detector could be a temperature measuring instrument. It converts temperature into the electrical charge. Thermo-couples use 2 totally different conductors that contact one another at one or additional spots. Thus, it produces voltage. Thermo-couples are usually used as temperature sensors. It lives and controls the temperature like within the case of Engine agent Temperature RTDs or Resistance Temperature Detectors conjointly measure the temperature. However, they are doing therefore by correlating the resistance of the RTD part with temperature. RTD part is created of pure metals like the Pt, nickel or copper. Associate air-con A Hall-Effect detector contains an electrical device that varies its output voltage consistent with the field of force. Typically, Hall-Effect sensors discover the speed or rate. The positioning applications in vehicles use this sort of detector. So, they're used for police work the shaft speed or its position. A contemporary automobile has the subsequent engine sensors: Thus, when shrewd the fuel amount, the engine computer unit  sends signals to numerous relays and actuators. They embody the Ignition Circuit, Spark Plugs, Fuel Injectors, engine idleness air management valve, and exhaust Gas Re-circulation (EGR) valve. Thus, it extracts the most effective doable engine performance whereas keeping emissions as low as doable. since all the sensors connect with the engine computer unit, in turn, it may monitor them for a malfunction.

ENGINE IMMOBILIZER

ENGINE IMMOBILIZER

ENGINE IMMOBILIZER DEVICE

A device which is directly connected to Engine Computer Unit and act as a security system and prevents the signal or current to pass and ignition take place. Its a chip which now a days every car have but at unknown place the simplest form of this security system is present in low rated vehicles.

SUZUKI MEHRAN but in latest and high rated vehicles have complex and most reliable engine immobilizer.

CONTROLLER OF IMMOBILIZER

As its a security device and its controlled by remote and finger print in complex and high rated vehicles have voice controller also.

WORKING OF IMMOBILIZER 

As its a chip inside the computer of the car or somewhere else in car or vehicle that chip have certain type of frequency when the key is inserted in the car to start that key also emits certain type of frequency and when both frequencies matches the ECU of car allows the engine to start. EVERY key have its own frequency. 

Still in low rated car this system is not that much successful but in high rated car vehicles like BMW, MERCEDES etc. have very strong and anti-theft system which is impossible to brake.

Every key of immobilizer is different with respect to codes those keys which have codes inside them. They are expensive and can not be made easily with simple key maker. 

    

WRONG BATTERY TERMINAL CONNECTION

WRONG BATTERY TERMINAL CONNECTION

Connected your car battery with wrong terminal.Yes , some serious scene will  happen if your car does not support or have ECU fuse.

How to connect battery

First of all one should always remember the red point is positive and addition cap is there always connect the positive + side of your car battery to that RED wire. Your battery terminals and wire should be connected in a such way that there should not be any gap or lose situation or else battery terminal will gets spark that could be very dangerous.

Safety measure

While connecting the battery  if you are holding any sort of iron equipment PLEASE get rid of it. In most cases when car does damages to wiring is when connecting battery and the worker is holding an iron equipment which accidentally touches  body of car and damages happen.

If there is wrong terminal battery have connected

There will be two things

1 If your vehicle is not supporting the ECU system or does not have ECU then wiring of your car will be damaged. You can only fix it by changing your whole car wiring cables ONLY.

2 If your car support the ECU controller or have ECU in engine. Mostly now a days every car have ECU  controller there will be a MAIN FUSE bigger than 40 AMP that fuse will destroy to have rest of cars wiring and ECU and important parts. JUST pull out that fuse and put a same number of  AMP fuse in it your car will start.

WHICH IS BEST METHOD TO REPAIR PUNCTURED TYRE?

WHICH IS BEST METHOD TO REPAIR PUNCTURED TYRE?

Tyre being essential part of the automobile. In handling of  any vehicle good quality tyre is necessary. What if your vehicle tyre gets punctured? What if you repair the tyre but its not of that quality which is required.
Their are two methods:-

1. Needle repair

1. Sticky Rubber repair 

well both of the methods repair the tyre but repairing quality and time require to repair is different:-

NEEDLE REPAIR

Needle repair is easy and quick method but this method can cause sewer damage to tyre strength and quality and damages the inside wires of tyre. But it is efficient in repairing. Later on sometime the tyre gets puncture again because the volume ofp hole increases.

STICKY RUBBER REPAIR

In sticky rubber repair the tyre still have good quality to drive and have good strength and durability

but it consumes more time than other method. The sticky rubber is attached to puncture place placing hot iron above the patch. This will remain for long period.
